are spinning their cocoons. June 12. Forest tent-caterpillars are still 

 spinning their cocoons, many trees have been defoliated by them. Eggs 

 of the elm leaf and potato beetles are hatching in limited numbers. 

 June 19. Potato beetle grubs are very abundant, the forest tent-caterpil- 

 lars have all disappeared. June 26. Potato beetles are very numerous 

 and destructive. Elm leaf beetle larvae are nearly full-grown. Fall web 

 warms [Hyphantria cunea] are numerous on appletrees. Both 

 house fly [M us c a d omes ti c a] and horn fly [Haematobia 

 s err at a] are very numerous and annoying. July 10. Grasshoppers 

 are exceptionally abundant. Adult elm leaf beetles have appeared. 

 Aug. 7. Grasshoppers are now feeding on late planted corn, the 

 meadows having turned brown from the drouth. Green cabbage 

 worms [Pier is rapae] are exceptionally numerous, some plots being 

 ruined by their ravages. Elm leaf beetle has apparently disappeared 

 with the first brood. The work of this insect on unsprayed trees was 

 as bad as last year, if not worse, American elms suffering as much as the 

 European species. This insect has not spread to elevations 200 feet 

 above the Hudson river. Sep. 11. Cabbage worms are doing serious 

 damage to the crop, nearly destroying many large plots. Oct. 9. 



Broome county (J. Mace Smith, Binghamton). Appletree tent-cater- 

 pillars [Clisiocampa americana] were seen for the first time Ap. 

 25. The buds of appletrees and wild cherry trees did not open till a 

 week later, and the caterpillars spun small nests and did no feeding. As 

 the weather warmed, it was seen that a large number of the egg belts had 

 hatched. The orioles and the waxwings do more than any other birds to 

 destroy these pests at this time. May 11. The cold weather did not 

 kill the caterpillars in this locality, and they are at work as usual. May 

 19. Appletree tent-caterpillars have been dying in large numbers during 

 the past week from a bacterial disease. Forest tent-caterpillars 

 [Clisiocampa disstria] are much more abundant than last year, 

 but they do not appear to have done much damage. [Euvanessa 

 antiopa] the spiny elm caterpillar, is much scarcer than last year. 

 June 9. The young of lightning leaf-hoppers [Ormenis pruinosa] 

 were observed in considerable numbers, uniting in a general gymnastic 

 performance, the air being filled with them as they jumped up and down. 

 They appear to do no particular harm. The tussock moth [Notol- 

 ophus leucostigma] is present in such small numbers as to cause 

 no appreciable damage. The sugar maple-borer [Plagionotus 

 speciosus] is very common and probably causes considerable injury.
